Meat Eating Behind Evolutionary Success of Humankind, Global Population Spread, Study Suggests

Summary: Carnivory is behind the evolutionary success of humankind. Earlier humans started to eat meat and hunt their new and higher quality diet, which meant that woman could wean their children early. The woman could then give birth to more children during their reproductive life, is a possibility contribution to the population, that gradually spreads over the world. "This has been known for a long time. However, no one has previously shown the strong connection between meat eating and the duration of breast-feeding, which is a crucial piece of the puzzle in this context. Eating meat enabled the breast-feeding periods and thereby the time between births, to be shortened. This must have had a crucial impact on human evolution," says Elia Psouni of Lund University.

Critique: It was good, just different that humans had to hunt for their higher quality diet that was meat.

Impact: Im not quite sure how this could inpact people or the world, but it probably will in the future.
